To all whom t may concern:

Be itknown that I, KINTARo MIYANAGA, a subject of the Emperor of Japan, and a resident of the city of Seattle, in the county of King and State of lVashington, have inrvented certain new and useful Improvements lin 'Envelops, of which the following 1s a iication.

y invention relates to envelops and has I for its objects the provlsion of a novel form.

of-closure and envelop, whereby the latter may be securely closed without applying an adhesive therebetween, and the formation of the envelop which facilitates the opening of the same.

` For a full understanding of the-presentl invention reference is to be had to the following description and the accompanying drawing wherein- Figure 1 is an elevation of an envelop in its opened position embodying my invention. Fig. 2 is a fragmentary elevation thereof in which the envelop is partly closed, and Fig. B'is a similar View showing lthe manner in which the envelop is finally sealed. With particular reference to the drawing, l designates the front side of-the envelop body, 2 and 3 the'side iiaps and 4 the bottom flap, the first noted side Hap projecting beneath its companion member, and the bottom fla overlapping the adjacent end portions o the aps 2 and 3. Adjacent the opposite end of ap 2, and cut therefrom, is a retaining or locking gage over an edge o a closure flap 6 carl'ried by the adjacent ed e of the front 1.

This flap 6 has 'an incline edge 7, extending outwardly from the front 1 and completely across the latter, which is adapted for engagement by tab 5 when the flap 6 is closed over the mouth* of the envelop. On its larger end portion, Hap 6 is provided with an offset tongue 8 adapted to overlie the front 1, when the said flap is engaged beneath tab 5, to be securely fastened to said front by the ostage stamp, as most clearly disclosed in ig. 3.

A slit 9 is provided between ap 2 andv frontl 14 communicatin `with the mouth of the envelop'. `This .s 1t is. adapted to -be closed by tongue 8 and is for the purpose of inserting the n'ger or instrument beneath ap 6 for removing the latter from under tab ff the` mouth t tab 5 adapted to enprovided with an extension 8 adapted to project belowthe stamp to facilitate the opening of the closure, as is obvious.

Having thus described my invention, what I claim as new, and` desirev to secure by Letters Patent of the United States of America, 1s
